and adapted as to be adjustable for form-l ing tiles of differentthicknesses, or to compensate for wear of the exterior contactsurfaces,and otherwise to improve the construction and arrangement of the machineto make it practically effective. This object we have accomplished bythe mechanismV which is hereinafter fully described and claimed, andwhich is illustrated in the accompanying drawings, in which:

Qur machine is intended to form hollow cylindrical drain-tiles from amixture of cement and sand, commonly denominated concrete, and thisinvention is an improvement upon the tile-machine for which we have apending application for patent in the United States Patent Office, ledMay 11th, 1908, underSerial Number 432,034.

The essential and important feature of our improvement is in the form.and adjustable construct-ion of the former-heads used to form theinterior of the tile in coperation with the outer mold-casing.` Saidformer-heads consist of two superposed cylindrical cores, an upper corehaving an integral axial sleeve adapted to be detachably secured upon ahollow cylindrical shaft 27 by means of a set-screw 67, `and a lowercore 43 havingk an integral axial sleeve adapted to be detachablysecured to the lower end of a solid shaft 1 by means of a set-screw 69.The two cores are relatively spaced but a narrow distance apart, whilethe solid shaft 1 is contained within the hollow shaft 27, the twoshafts being adapted to be rotated in opposite directions by means ofthe mechanism to be hereinafter described. Each of said cores isprovided with a plurality of forming-plates which are made adjustable ina direction leading outward from the axis of the core radially, as wellas being adjustable eccentrically. The upper core 55 has but two ofthese forming-plates 57, located oppositely and spaced apart widely toprovide a channel or chute between them for the tile-material to movetherein and be permitted to pass downward between the forming-heads andthe interior surface of the outer mold-casing 4l.

Each forming-plate 57 has a radial slot 5S to permit the securingtherethrough of a bolt 6() adjustably, the bolt being screwed into aseat in the upper horizontal plate of the core 55 with a washer 59seated between the head of the bolt and the top of the plate 57. Thenthe bolt 60 is turned to loosen its clutch upon said plate,l the lattermay be moved radially outward, or may be shifted on the bolteccentrically as desired, or adjusted in both ways. The outer portion ofeach plate 57 'has a depending flange which is spaced away from theouter surface of the cylindrical part of the core 55 by means ofadjust-ing screws 65. The forward portion of the outer side of each ofsaid flanges is beveled off downwardly and inwardly, which permits themoving fia-nge to grasp and compress the tile-material and form itagainst the interior surface of said outer moldcasing.

The lower core 43 is provided with a plurality of forming-plates 63,which however, are somewhat dissimilar from the plates 57, in this, thatthe depending flange of each plate is not beveled, but is increased inthickness gradually beginning with its forward end. Each flange is atits forward end bent inward toward the core 43. Each plate 63 is oricedto receive a bolt or machine-screw 62 extending through aislot 68 in theunderlying core-top, the washer 73 being interposed between thebolt-head and the under face of said core-plate. The plates 63 areadjusted by turning them on said bolts, or

IOS

by moving them in or out radially when said bolts are shifted in saidslots. The spacing apart of the depending fianges of the plates 63 iseffected by means of the adjusting-screws 66. A sufficient number of theplates 68 is provided to have them arranged continuously about the core43, with very little if any spacing apart of such plates. The outercurves of the plates are eccentric to the core axis, and the radialrecession of the tianged forward edges permits them to grasp andcompress the tilematerial and rub it smoothly against the inner wall ofthe outer mold-casing. The adjusting of the plates 57 and 68 radiallyoutward permits either of taking up any loss of the surface thereof byfriction, or allows them to be adjusted to vary the thickness of thetile. The shifting of such plates eccentrically permits of an adjustmentsuitable within the hollow shaft independently. Said i shafts arereceived in bracketed bearings 7 and t attached to a backing-plate 8.This back-plate is fastened to the forward ends of horizontal beams 32and 33, such beams being supported by the uprights 49 and of the frameof the machine.A

the bracket-bearing 7, and is furnished at its upper end with abevel-pinion (l. The solid shaft l extends upwardly prolonged above thepinion 6 and its upper end has a fillet which rests upon an upperbracketbearing 2 attached to the backing-plate S. A bevelpinion 3 issecured to the shaft l under the bearing 2. A horizontal shaft 5 isrotatable in bearings 9 and 1S supported by the machine-frame, and hason its forward end a bevel-gear wheel 4: in mesh with the bevelpinions 3and 6. An idlerpulley 14 is mounted on said shaft 5, and carries afriction-ring or seat 19 adapted to receive a friction-cone 13 when thelatter is shifted in one direction. Said friction-cone and its hub isslidably but non-rotatably mounted on said shaft 5, to slide over thefeather 74 on said shaft. Said hub has an annular groove to receive theforked ends ll of the upper member 2O of a bell-crank 22, which ispivoted at its angle on a stud 23 extending from a hanger l0 secured tothe beam 32. The lower member of said bell-crank lever ispivotally-connected at 2l to the upper end of a connecting-rod 26, thelower end of the latter beingl pivotallY eonneeted at 29 to the shortrear member litt) of a hznid-lever i253, the latter beine' niediallypivoted to the beam vl. The leze 28 is notched at a point on its loweredge to engagea pin l1*- on the plate .Q to limit its downward movement.ldlhen the lever 28 is thrown either down or up the pivotal connection29 is moved past its deadcenter, and the friction-enne t3 is thrown intoor out of contact with the friction-ring or if). The pivoted joints ofthe eonnected parts are so contrived as to wortY somewhat stit'lly, andthus hold any positions in which they may be placed at an); time withoutregard to the, influence of gravity. The power-pulley l-lthus impartsrotation to the shaft in a well-linmvn. manner, andl thebevel-gear-wheel -lthen rotates the lievelpinions 3 and (l in oppositedirections. imparting the same movements to said .sha fis l and 2T andtheir respective care-plates if .in upward ii1o\eineiit of the lever and43.

throws the connection 2f) the other wa)v past the dead-center, and the.friction-cone is i detached and held apart from the frictionring 19.stopping the rotations of the .shaftsI l and 27.

The outer mold-casing gl-l is supported ou the forward end of averticallyY rm'vable table or carriage 5G, the forward end of saidcarriage being forn'ied in the shape of a ring with an annulus -1t2 tohe the seat of the lower end of said casing. 'lhe circular opening ofsaid ring T2 is of they same diameter as thc outer diameter of thecylindrical exterior of the former heads and their forming-plates. Thecarriage .iti has sleeves y and 53 whose inner hollows 'Tl and T() re-The hollow shaft 27 terminates just above spectively fit them to movefreely over the, uprights i9 and o2.

25 represents a horizontal sltwve-bearingv supported by the uprights 52and -ll. and

i in which a short sha ft 24 is rotatably mounted. large gear-wheel 'lois mounted on said shaft: 2land meshes with a pinion li' en thepower-shaft 5. cranl--pin ,l5 projects froin the forward fare of thegearwheel lf3, and on it is piv -tally mounted the upper end ofconnecting-rml il- 3. the lower end of the latter being` pivoted on apintle secured between the lugs ft-T on the. earriage 5G. During onehalf of the rotation of the gear-wheel itl. the carriage atl is,elevated, and during the next half rotation the carriage is lowered,thus movingthe moldcasing -l-l up and down alternateljv about theforming-heads on the said shafts l and 27. is a bar whose hollow sleevesElfi and are slidable vertically over the uprights 49 and respectivelyabove the carriage oo, and on whose projecting;` forward end a smallhopper t() is mounted. ythe inner periphery of this hopper communicateswitl: and is of the saine interior diameter as the mold-casing 4l. Therear 'ardly-projeeting lOtl lifi

end of the bar 35 is vertically oriticed to permit the passage of afixed vertical guide-bar 36, the beam or bar 35S-moving over saidguide-bar, but being limited in its downward movement by a projection orengagingmeans such as a nut 37 on the lower end of said guide-bar. Thenthe carriage moves upward its superposed casing 41 rises till its upperedge engages the overhanging hopper At() and lifts the latter with it tothe filling position indicated by the Fig. 1. Mixed materials are thendeposited in the hopper flowing thence into the casing, and as thelatter descends, such materials pass between the former-heads whoserotating' engaging means form a tile between themselves and said casing.When the casing has lowered a certain distance, the nut 37 engages thebar 35, and disengages the hopper from the casing, the latter movingstill farhtre downward to a position where the casing and inclosed tilemay be removed and an empty casing substituted.

it will be seen that the adjust-able forming-plates on the former-headcores may be adjusted without removal from the machine while at rest,and that they may be adjusted to take up wear and also to vary thethickness of the tile, and that their relative positions with regard toeach other and such cores may be varied as to effect in use the amountof compression of the material desired while forming the tile. Theopposite rotating of the former-heads also eifects a more completerubbing action and resultant homogeneity in the tile.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is:

1. ln a tile machine, in combination, a mold-casing, concentric shaftsoppositely rotatable in said casing, a core secured on each shaft andlocated one above the other, and cecentrically adjustable former-platessecured to each core, said cores and attached plates working within saidcasing and spaced apart therefrom.
